LDAP login

Hello, i'm wondering if we can use LDAP user connect, within a single form in a process?
I used LDAP authentication configuration | Bonita Documentation (bonitasoft.com), but didn't found this part

Configuration steps

Changing Bonita authentication service

The default Bonita installation comes with an authentication service implementation based on the Bonita Engine database. In order to activate Active Directory/LDAP authentication the service implementation needs to be changed. To do this, edit bonita-tenant-sp-custom.properties.

You will need to perform following changes:

• Comment out the authenticationService line

• Add this new line: authentication.service.ref.name=jaasAuthenticationService

In which file should I set this property? And I have no setup folder inside bonita folder

Thanks
